Ensures correct results are returned for conditions and criteria for a given telemetry datapoint (#2904)

* Ensures that results for a specific datapoint are evaluated atomically.
* Remove generating timestamp for telemetry data
* Get results directly instead of using events
* Refactor all/any telemetry criterion to use new evaluator
* Use current timesystem to compare latest
* AllTelemetryCriterion extends TelemetryCriterion
